  2. Feedwater heater - Wikipedia

    en.wikipedia.org/wiki/Feedwater_heater

    A Rankine cycle with two steam turbines and a single open feedwater heater. A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler. [1] [2] [3] Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system ...

  3. Water heating - Wikipedia

    en.wikipedia.org/wiki/Water_heating

    Domestically, water is traditionally heated in vessels known as water heaters, kettles, cauldrons, pots, or coppers. These metal vessels that heat a batch of water do not produce a continual supply of heated water at a preset temperature. Rarely, hot water occurs naturally, usually from natural hot springs. The temperature varies with the ...

  4. Boiler feedwater - Wikipedia

    en.wikipedia.org/wiki/Boiler_feedwater

    The water is reused and needs to be treated to continue efficient operations. Boiler water must be treated in order to be proficient in producing steam. Boiler water is treated to prevent scaling, corrosion, foaming, and priming. Chemicals are put into boiler water through the chemical feed tank to keep the water within chemical range.

  5. Boiler feedwater pump - Wikipedia

    en.wikipedia.org/wiki/Boiler_feedwater_pump

    A means had to be provided, of course, to put the initial charge of water into the boiler (before steam power was available to operate the steam-powered feedwater pump). The pump was often a positive displacement pump that had steam valves and cylinders at one end and feedwater cylinders at the other end; no crankshaft was required.

  6. Storage water heater - Wikipedia

    en.wikipedia.org/wiki/Storage_water_heater

    Solar heat is clean and renewable. This is the most modern system. Increasingly, solar powered water heaters are being used. Their solar thermal collectors are installed outside dwellings, typically on the roof or walls or nearby, and the potable hot water storage tank is typically a pre-existing or new conventional water heater, or a water heater specifically designed for solar thermal.

  7. Franco-Crosti boiler - Wikipedia

    en.wikipedia.org/wiki/Franco-Crosti_boiler

    The Franco–Crosti boiler is a modification of the conventional fire tube boiler design used on most steam locomotives. Unlike conventional boilers the heat remaining in the exhaust gases is used to preheat the water supply for the main boiler using a secondary heat exchange mechanism.

  9. Tankless water heating - Wikipedia

    en.wikipedia.org/wiki/Tankless_water_heating

    A hybrid water heater is a water heating system that integrates technology traits from both the tank-type water heaters and the tankless water heaters. [5] It maintains water pressure and consistent supply of hot water across multiple hot water applications, and like its tankless cousins, it is efficient and can supply a continuous flow of hot ...
